Longest driver in the world and pound for pound no one is close.
Looks like active pivot to me?

I agree with you 100%. Jamie Sadlowsksi has a very active pivot action. He couldn't hit the ball nearly that far using a reactive pivot action, which is a much weaker method of releasing PA#4.

Here is another link that demonstrates his amazingly efficient active pivot action.



I wish I had his degree of body flexibility. My swinging problems would be significantly improved if I had his degree of hula hula flexibility.

Jeff.

Jeff . . . . I think this whole hula hula deal is somewhat valid but . . . if that is your actual top . . . you could a) get your arms on a flatter plane and b) turn your hips . . . you got ZERO hip turn. Remember you have hula hula on both sides to keep your head centered. So flare your right foot some, straighten your right leg some on the backstroke and really turn your hips . . . . that will get your hands deeper. You ain't got you backfield in motion at all. YOu may not be able to turn your shoulders . . . but you can turn your ass.

Good stuff, Bucket . . .That's exactly what I saw.

Sure helps to let that Left Heel come up, too. Check each photo of these greats. And not a golf-related knee or hip operation in the bunch!

For all the 'modern' Flat Left players, tell me these guys got it wrong.

Thank you for offering me advice.

I understand why you are offering me that advice. A bigger hip turn in the backswing allows one to get the hands deeper and further back in the backswing. I have tried that maneuver. It does help me get my hands slightly deeper and that's advantageous.

However, I have zero hula hula flexibility, and if I over-rotate the pelvis during the backswing, then I have to perform a greater amount of rotary pelvic movement during the hip squaring phase of the downswing, and that really throws my right shoulder into a roundhousing action that causes me to come wildly OTT (due to my lack of hula hula flexibility).

Jeff.

Boss . . . . That don't make sense . . . . when you DON'T rotate your hips what do you do? Looks like if you don't turn your hips and you spin then you would even MORE wildly swing your hands over the top. The hip turn would give you more "lattitude" to spin because you have more "range" to cover before you hands get too far out to be actually over plane. There's a difference between over the top and swing over your backstroke. Most players hands go over where they did in the backstroke.

Try this . . . . make a bigger hip turn and DON'T TURN AT ALL . . . just go FORWARD and release #4. Not to get this debate going . . . but it sounds like you have no trouble spinning . . . so go forward and swing your arms down (sorta like Tomasello).

Not releasing #4 and spinning is a big recipe for shooting the hands off the plane. Your hand have to go DOWN THE FACE of the plane . . . .a big piece of that is releasing #4 (master accumulator and all) . . . that with tilting your axis.

I think you got hula hula way mixed up . . . . can you stand up straight and scratch your right thigh below you pants pocket?

Jeff you just gave me something to look at. I can't stop coming over the top especially with the longer clubs. The only way I can remotely control my OTT tendency's is to stop my backswing short and keep my hands low. Your elbow description may be the little thing I need to focus on and change. Normally my elbow flies back behind my shoulder and back. I took some practice swings in the house focusing on the elbow and not letting it get back behind me. It really felt like I was flinging the right arm unlike before. It feels weird but at the same time it felt a lot smoother. I can't wait to look into this on the range.

Thanks

**Edit** Just came back form the range. The elbow thing wasn't the magic OTT driver cure I was hoping for. With that being said, I seemed to hit the wedges a little more accurate as well as the irons. It seemed I was making a smoother swing and a little cleaner contact. I was still pulling the driver... UGGGGHHH. I guess I'll wait till Christmas so I can finally unwrap and view the Alignment Golf DVD. Hopefully I'll then be able to diagnose what's going on here??? Back to the 4w and hybrid off the tee box...

It is my mistake for posting that capture frame from a swing video lesson where I didn't turn my hips but just assumed a hitter's end-backswing position to demonstrate a point in my swing video lesson on hitting (for my personal website).

Here are capture frames from a swing video of my driver swing.



I think that I get an adequate hip turn. However, I cannot get my left arm across my chest and my hands far enough back, so my left arm bends at the elbow and also slides up my chest (off plane) and my hands get too high above my neck causing an across-the-line clubshaft position. I placed a red X to show you where my left humeral head is located.

I didn't want to focus on my personal (imperfect) swing. I merely wanted to talk about biomechanical factors that may cause a golfer to choose a reactive pivot swing rather than an active pivot swing.

I think that if you consider my test for determining hula hula flexibility, that I am correct to state that I have zero hula hula flexibility - defined as an inability to turn the hips forward in the downswing without immediately feeling the shoulders turn passively due to forces transmitted up the spine. If someone holds my right shoulder back in that test, then I cannot rotate my pelvis forward even 1 inch.

Here is another biomechanical factor that I have never seen discussed re: limitations in getting your hands far enough back in the backswing - a limitation being due to left scapula movement limitations rather than an inability to rotate the upper torso. I think that many people regard a shoulder turn as being equivalent to an upper torso turn. However, I think that the left shoulder socket can move >3-4" further than the upper torso turn due to the sliding of the left scapula forward.

Here is an example.

Anthony Kim



Here is a capture image from that video



I have placed a red "x" at the location where I think that his left humeral head is situated. Can you see how much he can slide his left scapula forward across his left upper back thus allowing his left shoulder socket to get far more around to the right (compared to me).

I personally have far more limitations in left scapula movement than upper torso rotational movements and it is the main reason why I cannot get my left arm/hand far back.

Jeff.

Is the Slammer a bit arched at the end there? It does not look in-line. Is it the angle or just my ineptitude
